`Au'roivioiariin HORN.

Application filed August 6, 19.23. vSerial No. 655,810.

My invention has for its object to provide an electromagneticallyoperated horny wherein-the parts are so constructed that they may beeasily assembled and adjust-` ments may be easily made, and wherebyefficient liorns may be manufactured at a low `cost of production. Y

A horn containing the invention is illus'- trated in the accompanyingdrawings and is described in thefollowing description.

Figure 1 of the drawings is a electroi'nagnet, the covering shelll beingshown removed therefrom. Fig. 2 is a side` view of the horn. Fig. 3 is asectionalview taken on the lineB-B indicated in Fig. 1. Fig. 4illustrates a means whereby two of the parts maybe readily lockedtogether in the manufacture of the horn. Fig. illustrates a side view ofthe horn a part of the clamping fiange being shown to clearly show thethree main parts of the horn.Y 'Fig 6 illustrates a vertical sectionalview of. the

horn takenbetween the connector plate and tion shown, a supporting plate4 is also se-l cured in ypositionv in contact with or in close proximityto the diaphragm 2'by spinning or crimping the edge portion of theresona-V V tor of the horn over theedges ofthe plate".

and the diaphragm.

The supporting plate Liis provided with a1 plurality of projectingparts'that arestruck"A up from the plate 4 on which the parts of thestructure are supported so thatv they may function one with the other.rThe electromagnets 5 and a connector plate 6 are sup-,V

ported on the. parts 7 that are struck up from the plate 4i. These partsare secured together by riveting the ends of the cores 8 of the magnetafter they have been inserted througdi the parts 7 and a flange 9 thatis struck up from the connector plate 6. The other end of the connectorplate is also provided with an upwardly extending flange 10.l andbinding posts 11 are securedy to the view of the Fig. 7 illustrates asidey `flange 10.y They are insulated from the connector plate 6 bysuitable insulating mate-vV rial 12. yWires from the electroinagnets areconnected to the binding posts and alsoto connecting'members 13 and 14e.Thek cone nectoi' member 13 is located at the end of a leafspring 15 andoperates to secure one end of the spring to the connector plate 6. Thespring 15 protrudes through an opening'lG formed in the body of theconnector plate and in the flange 9, andV beneath a lug 17 that isfoimed from the space that. forms the opening through which'the spring15 extends to a point between the eleetroinagnets This y f 1,679,745,yTEsPATENT OFFICE.

leaves a small amount of metal at the upper corners of the opening 16that may be readily vbent by the use of a pair of pincersv to jad'justthe position of the lugli relative to the spring 15. A contact 18 issupported on the spring 15 and .acontact19 is Siipported on the lug-17and suitably insulated therefrom. The contact, 19 electrically connectswith the connector member 14.- that is connected to one oftheelectromagnets 5V7 so .Y

that the position of the contacts 18 and 19 may be readily adjusted bysimply :gripping that4 portion of the flange 9 located above the lug 17and bending the {lang/eat `this point so vas' to move the lugA 17,either up or down or swinging it ylaterally or evengrearwardly vorforwardly to properly radjust the contactsv 18 land 19 relative to eachother to produce a full`- and complete contact oversubstantially theentire areas of the contacting surfaces of the contacts.

3 The armature 20 is pivotally supported in.V

the parts 21 that are struck` up from the plate 4., vThe armature 2O isprovided with an arm l' 22 that extends substantially to the center ofthe diaphragm 2. The end x23 of the arm7 being turned substantiallyalong the axis of the'hornand entering. anopening `through the plate 4,is positioned vfor striking the horn when the magnets are energized. Thearm 22'of the armaturer 20 is provided with a rivet 24 having a flangedhead 25 thatV en? gages-tlieend ,of the leaf springl'." A dat vspring26`is secured to the arm 22 by means of the riveted member yThe spring26 enters anl opening formed in the portion 27 that is 4struck up fromthe .platey Li. The spring 26 is so bent that wlien;the armature isinserted in place` and' the spring is insertcd in the opening 28 formedin the portion 27 the spring operates to elastically hold or retain thearmature 2O in the desired posi- Cil tion relative to the poles of theelectromagnet.

The port-ion Q7 is also provided with a slot or cut 29 that tits a slot30 formed in the connector plate 6 so that when the magnets 5 and theconnector plate 6 are secured in position the connector plate isglirstslid over t-he end o' the portion 27, while at the same time it is movedlaterally so that the slots 29 and 30 will permit interengagement of theend of the portion 7 with the body portion of the connector plate 6, andthen the ends of the cores of the magnets are riveted to the connectorplates after having been inserted through. the portions 7 that arest-ruck up from the plate 4.

The invention thus provides a construction that may be readily andrapidly assembled in the manufacture ot automobile horns. The connectorplate Gcarries the connecting parts, such as the binding post 11 and thewire connecting members 13 and 14. These `are the parts that areconnected to the terminals ot the coils of the n'iagnets 5. Theconnector plate 6 and the parts connected therewith may be readilyassembled in position and then placed on the supporting plate andsecured in position by means of the rivets that may be formed at theends of the cores of the magnets. The wires may then be connected to theconnecting members and to the binding posts. This completes theassemblage of this part oi the structure. The armature may then beinserted between the portions 21 of the plate l and the portions 21 benttowards each other so as to engage the pivot `pins of the arma-ture andthus pivotally support the armature in position. At the same time thatthe armature is inserted in position, the spring 26 'may be inserted inthe opening 28 of the portion 27, and the hanged head 25 may be insertedover the end of thev spring 15 and in position to engage the spring whenthe armature is operated by the electromagnet. Therefore to assemble theparts the electromagnets are riveted to the connector plate through theflange 9 of the connector plate and the armature 20 is inserted inposition, and the portions 21 are bent up so as to engage the pivot pinsof the armature.y

The Y only adjustment required in the mechanism is the position of thecontacts 18 and 19 relative to each other. In order to make a full andcomplete contact, that is, in order to cause the `contact 18 to strikethe contact 19 squarely, some adjustment may be required. This may beaccomplished by bending the portion 31 of the iange 9 located directlyabove the opening 16, whereby the lug 17 may loemoved lateral or bentupward so as to enable the contacts 18 and 19 to make good contact witheach other. The invention thus provides an exceedingly eilicient hornthat may be manufactured rin large quantities at a low cost ofproduction. The cover 32 may be secured in position by lugs 33 that arestruck up from the supporting plate 3. Preferably three such lugs areused to engage a 'flaring edgeA portion that is formed on the shellcover 32. The operative parts of the mechanism may thus be covered byinserting the edge of the cover under two of the lugs and snapping theedge under the third lug.
